BARBED METALLICv FENCING.

SPECIFICATION forming part of Letters Patent No. 244,726, dated July`26,1881.

' i Application filed January 24, i880. v

To all whom it may concern:

Be it known that I, THOMAS V. ALLIs, a citizen ot the United States,residing at New York, in the county and State ot' New'York, haveinvented a new and useful Improvement in Barbed Metallic Fencing, ofwhich the following is a specification.

This invention consists in the combination, with a rod having barbs onone'side only and a narrow web along the sameside between the barbs, ofa tin on the opposite side of the core which shall be of the proper sizeto counteractl the unequal effect of the barbs and webs between them onthe rod while twisting. Were this tin omitted, the rod would assume aspiral or cork-screw shape in consequence oif a preponderance of metalon one side, which is objectionable. I propose to add enough metal inthis tin tothe opposite side of the rib or core to balance the barbs andwebs between them, so that the rod will be straight when twisted.

The narrow webs between the barbs serve several purposes: rst, in theformation of the barbs by stamping or punching them from the wide iinthe strength of the core is not impaired, as it wouldl be if the cutswere made into or close to it; second, greater surface is presented toview; third, it has a tendency to make the rod elastic 5 fourth, itpermits broader cutting-surfaces to the dies, which makes them moredurable.

The size of the barbs and webs between them maybe varied to suit thewants and ideas of different localities and countries. Conse- .quentlythe balancing-tin must be correspondingly varied in dimensions.Therefore I do not confine myself to any special size of iin on the coreopposite the barbs.

It is obvious, where there is a row of barbs 4o on each side of a rib orcore with webs between them, that one balances the other, and thisinvention applies only to barbed fence-rods having` a row of barbs onone side.

Figure I is a side view of a rod having a broad iin on one side, fromwhich to form thev barbs, and a narrower one on the opposite side,intended for balancing. Fig. 2 is a side view of the same having barbsformed on it, and Fig. 3 is a side view of the finished rod with thebarbs .cutand said rod being twisted.'

A represents the core or body; B, the wide fins out of which the barbs Dare formed, and O a plain rib or balancing-'tin to balance barbs D, andwebs B remaining between the barbs D when the surplus metal is cut away.

This invention differs from all others in metallic barbed fencing, inthat it consists of the application of a plain unbarbed balancing-tin toa rod having one row of barbs along one side only, between thebases ofwhich barbs there is left'a narrow .web of the iin, out ot' which thebarbs are formed, said plain n'being opposite to the barbs and theirconnectingwebs, and being equal in capacity to said connecting-webs forcounteractin g their tendency to make the rod twist. crookedly when notso balanced.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is v A barbed metallic fence-rod having a single rowof barbs with narrow ribs B between them,andaplainrib,O,ot'samedimensionsinbreadth and thickness as said ribs B',on the opposite side of the core thereto, substantially as specied.
